Mechanical seal for slurry pump should pay attention to the problem?

Mechanical seal for the slurry pump should pay attention to the problem One: the friction material of the different effects: the seal almost all media, reducing the accuracy of the installation requirements. 1: The traditional mechanical seal rings are made of hard materials, these materials are characterized by hard and brittle, fragile under the impact of external forces. PNM seals in the static ring to take the filler, the material is PNMS001, the material is soft and impact resistant. Moving ring made of wear-resistant steel, not easy to damage. 2: Foreign particles are easy to wear debris caused by the friction pair, the life of the machine seal by the particles of a great impact, sometimes the seal seal failure is the instant formation, so the requirements of high water cleanliness. PNM seal: foreign particles in the NN surface can not do long-term movement, immediately passive ring into PNMS001 friction pair, the overall seal is not affected, so the scope of the substantial extension. 3: During installation, it is necessary to ensure that the friction surface is perpendicular to the shaft. The deviation can not be too large. Otherwise, the movement ring can not be completely in contact with the stationary ring during the rotation, and the phenomenon of leakage occurs after the installation is completed. PNM seal: friction match surface is rapidly formed during the friction, no matter how the installation, PNMS001 surface of the high and high points in the area under the action of dynamic plastic ring through the plastic deformation collapse quickly, so that the PNMS001 and the whole surface of the dynamic Torus reliable contact, this time to achieve the desired state, this process is completed, so the installation accuracy is not demanding. 4: Machine sealing is not widely used the biggest reason is: mechanical seal any one of the components damaged, you must dismantle the pump replacement, and other parts together to replace, heavy workload, long time, and the astonishing waste. PNM seal: moving ring system as long as properly designed properly selected materials, can be used for permanent use. Only static PNMS001 ring, rubber ring easy to damage, PNM structure can be removed without replacement pump these wearing parts, like replacement Packing as convenient, greatly saving time and money. Mechanical seal for the slurry pump should pay attention to the problem II: The moving ring system almost all pumps to adapt to the working state 1: In order to solve the long shaft sleeve affect the moving ring metal parts, rubber parts of the axial movement problems in the PNM seal A stainless steel thin-walled sleeve is attached, which is in contact with the shaft and fixed on the sleeve. The axial moving part of the movable ring moves on the stainless steel sleeve. The traditional mechanical seal structure is not a good solution to this problem. 2: The moving ring is designed as a radial floating structure, which can correct the radial runout of the shaft with a correction amount of up to 0.7-0.8 mm. This is the function of the traditional mechanical seal ring system does not have. Traditional mechanical seals do not solve this problem. 3: PNM seal to take a large fork drive, this drive ensures reliable transmission of torque, regardless of rotation, can well protect the floating installation of rubber parts. Some traditional mechanical seal structure is very simple, completely ignored the problem of floating O-ring damage. 4: The unique use of rubber parts can make rubber parts easy to open replacement. Touching mechanical seal also did not consider this issue.
